Patent DE-2723569-A1 (DE)
Inventor: KOCH WOLFGANG
IPC: A47B87/02
Filed: 1977-05-25
Abstract: The invention relates to a sales shelf unit for paperback books, calendars, picture postcards, and similar articles having titles. The compartments and shelves (3) provided in each case for the individual articles are supported by a rear wall (4) which is of W-shaped cross-section, four rear wall sections (5) and (6) being provided in each case at an angle to one another. The shelves are arranged in the angles of the sections. Using such a shelf unit, angles or edges can be utilised well since, due to the W-shape, the back of the rear wall can grip around such an edge or be placed in a corner. Good space utilisation thus results even in sales rooms with columns, projections or the like and, even on a wall, more paperback books or the like can be displayed with greater clarity due to the sloping position. <IMAGE>
